Today, I decided to prank my boyfriend by putting a pair of panties in his coat pocket. I stormed in and confronted him with the "evidence". I guess the prank worked; he broke down and confessed to cheating on me. FML

Agreed she deserved that. It sucks that you found out he was cheating on you but it's your fault for pulling that prank. You shouldn't do something like that if you aren't prepared to hear the truth, even if it was a joke.

That's really a very dumb thing to say. She doesn't deserve it at all. Maybe it was a retarded prank, but that doesn't justify what her ass wipe boyfriend did. The man is the only one in the wrong here. Big surprise there.

NOBODY deserves to be cheated on. She might have deserved the way she found out, that was a stupid prank, but in no way does she deserve being cheated on. At least you found out now, OP, so you can dump his ass.

#60 no, if she put ex-boyfriend it wouldn't make sense (How could he be cheating if he was her ex?) If she put "Now-ex-boyfriend" it would have partially ruined the end of the FML.
So im sure she meant to put 'boyfriend' ;)

It''d be a 'that awkward moment when' the situation occurred, but if he had been a competent bf, then it would been something to laugh about later.
Also, fyl op for discovering your ex was nothing more then a worthless piece of shit.

I'm pretty sure the only people who would be that upset about a simple prank like this, is super uptight and touchy little douche bags who probably really do have something to hide. Storming out like a little baby would hardly be a way to prove your "maturity". Just make you look even more ridiculous than the one doing the stupid prank.

But...I wouldn't break down and cry. If I knew he was joking, I would simply smile and say "shut up". If I thought he was serious, I would laugh and explain I have no idea how those got in there. Either way, once I found out it was a joke, I would take it that way; as a joke.
If you are the type be genuinely insulted, then it would be a nasty thing to do, assuming your better half would know that it's in your personality to get upset easily. But I'm going to go ahead and guess that the OP and her [ex]boyfriend were the type to joke a lot, leading to this kind of prank. Had he been innocent, it could have just ended in a laugh. The fact that it ended badly was not the OP's fault at all.

It's through this thread you really get to see how crappy the quality most of us guys really are. And how "mature" we think we are judgments of "oh she's so immature and stupid".
If you really love your girlfriend, AND YOU'RE ACTUALLY FAITHFUL TO HER, this is nothing. My girlfriend pranks me like this all the time, but I having nothing to hide from her, I play along and then just pull her in and kiss her when she pretends to start getting upset that I "cheated"; in a healthy, faithful relationship where THERE IS ACTUALLY TRUST, this would be an "issue" about as much as the issue of leaving the toilet seat up. And just in case another idiot comes along and mistakes the meaning of that, I mean that this shouldn't even be something to argue about for even two seconds.
My two cents of knowledge for this poverty-stricken thread.

If you're in a relationship you shouldn't be expecting to find out they're cheating for you, you shouldn't be getting ready to hear that kind of stuff cause both people should remain faithful. She probably just wanted to see his reaction and it was probably meant to be a little joke I don't see why people say she deserved it cause nobody deserves being cheated on in my opinion.

Or she thought he was cheating and this "prank" was the only way she could admit it to herself to confront him.
She doesn't deserve to be cheated on. She does deserve to find out that way if she is going to be childish and try to start a fight.

however, how stupid would the bf have to be to fall for that? if my gf did this to me, I think I would 1: know what panties the girl was wearing, 2: know what panties my gf has, and 3: know she didn't put them in my pocket!

FYL for having a cheating boyfriend. However, you should have been prepared for that possibility if you were gonna pull a prank like that. Unless he absolutely never gave you any kind of hint or reason to suspect... in which case, double FYL.
